Bear in mind that an active component may have a high LD50 placing it in a Poisoning Group II, III, or IV yet likewise have destructive eye/skin impacts that take concern and location it in Poisoning Group I.

All pesticide poisoning worths, including the LD50, can be located on the item's Product Safety and security Information Sheet (MSDS) - bed bug spray.
